The current regulation requires non-EU applicants to have health insurance coverage before departing. It must cover costs for medical treatment abroad and for the entire period of your exchange. In order to prove you are covered you need to provide a declaration from your insurance carrier confirming coverage abroad for the minimum amount provided by the law. Please note that Bocconi university does not sell medical insurances. However, the ISD will provide you with more information on health insurance policies you can subscribe to. The duration of a permit of stay cannot exceed the duration of a health insurance coverage period.
